Spain: Beaches Closed Due to 'Blue Dragon' Sightings

Alerts have been issued in Spain following the appearance of a rare and dangerous marine creature known as the 'blue dragon' (Glaucus atlanticus) on the shores of the Costa Blanca.

In the Guardamar del Segura area, local authorities raised red flags and banned swimming along an 11-kilometer coastline after two creatures were found on Vivers beach.

Mayor José Luis Sáez warned that the 'blue dragon', despite its small size (3-4 centimeters) and striking blue color, is extremely poisonous and dangerous to humans. Citizens are advised not to touch the creatures, even with gloves, and to notify the authorities if they are spotted.

The sting of the 'blue dragon' can cause intense pain, dizziness, nausea, and vomiting, and in some cases may even lead to a fatal reaction. Authorities recommend immediate medical attention in case of a sting.

This is not the first time Spanish authorities have closed beaches due to dangerous marine species. In 2018, part of the Costa Blanca was closed due to the appearance of Portuguese man-of-war.
